Polyethylene is a polymer formed by the polymerization of ethylene monomer radicals, referred to as PE. PE synthetic materials derived from petroleum, oil-rich due to its production ranked first. Polyethylene is a relatively late age of industrialization, but the fastest-growing plastic varieties. The earliest industrialized varieties of LDPE. Currently, polyethylene varieties are: low density polyethylene (LDPE), high density polyethylene (HDPE), linear low density polyethylene (LLDPE), high molecular weight polyethylene (UHMWPE). In addition, there are vinyl acetate (EVA), and chlorinated polyethylene (CPE) and the like. (PE-HMW) ultra-high molecular weight polyethylene average molecular weight of 500,000g / mol or more, high rigidity, toughness, mechanical damping resistance, wear resistance, corrosion resistance, easy to weld, with balanced performance. -200 Degree temperatures, there are still good impact resistance, used in food, machinery, chemicals, textiles, packaging machinery. Specific gravity 0.96
